Description

A disease early warning device for radiotherapy computer lab

Technical Field

The utility model belongs to medical equipment relates to a disease early warning device for radiation therapy computer lab, is a real-time supervision and alarm system of the patient vital sign of radiation therapy computer lab, is applicable to the transmission of patient's biological information's real-time monitoring and patient information of seeking help between radiation computer lab and the control room.

Background

Vital sign monitor: the instrument has the functions of non-invasive blood pressure (NIBP), pulse rate, Mean Arterial Pressure (MAP), blood oxygen saturation (SpO2), body temperature monitoring and the like. The product performance structure and the components of the product comprise a host, a blood pressure sensor, a pulse blood oxygen (SpO2) sensor, an extension cable, a body temperature probe and the like. The product has the functions of monitoring non-invasive blood pressure (NIBP), pulse rate, Mean Arterial Pressure (MAP), blood oxygen saturation (SpO2) and body temperature, and can be used for monitoring the non-invasive blood pressure, pulse rate, body temperature, non-invasive arterial blood oxygen saturation (SpO2) and body temperature in a normal mode and an armpit mode for newborn, children and adult patients. The product may be used in a medical/surgical ward, hospital, or other care setting.

The room for radiation therapy is now conventionally composed of a treatment room and a control room. When a patient is treated, only one patient is allowed to be in the treatment room and the lead shielding door is closed (radiation penetration is prevented), and other personnel such as doctor family members can only be left in a control room of a partition wall. The doctor can check the state of the patient in the treatment room in real time through video monitoring. In practical operation, we find that there is a great safety hazard left by only observing the patient in real time through video. When a patient is treated in a treatment room, the focus part of the patient needs to be kept relatively fixed, for example, a nasopharyngeal carcinoma patient wears a detachable fixed mask and is fixed on a treatment bed, a lung carcinoma patient wears a fixed body cover to be connected with the treatment bed, and the like. In the irradiation process, in case of asthma (patient tension or mask over-tight) and unexpected physical condition, the warning signal (shouting, motion limitation, etc.) of the patient can not be transmitted in time. At this time, it is not enough to check the status of the patient only by video monitoring, and the current deficiencies are summarized by sorting as follows:

1. the patient is fixed on the bed, the warning action is limited, and the warning action cannot be transmitted through video monitoring;

2. when a patient is in a treatment room, the vital sign condition can not be transmitted through video monitoring;

3. the wall between the treatment room and the compartment of the operation room has overlarge thickness, and the alarm sound of the patient cannot be transmitted to the operation room;

doctors and the like make small differences and the like to miss or not see the video monitoring.
